Working with the My Alerts display |
Select Alerts from the Designer Studio developer toolbar to view lines from the current Alert log on the server node produced by your own requestor session. (You can access the same display from the My Alerts link of the Performance tool summary display.)
This display is limited to the current Alert log; alerts in older logs are not visible. Depending on your log file systems settings, a new log may start each time a node is started, at specific time each day, or on another basis.
During your requestor session, a pop-up message appears briefly when an alert is triggered.
To turn off the pop-up feature, select Preferences > View from the Designer Studio Profile menu and clear the Show Alerts Popup checkbox in the My Alerts group.
